I thought one of the World Service radio stations was already on Livestation? Maybe I'm thinking of a different platform, or maybe it was for a limited period. Either way, we have a weekly reach of over 180 million listeners, when you add in the audience from the BBC World News channel it gives the Global News Division a weekly reach of well over a quarter of a billion people across all platforms. You don't get a reach like that by accident. We have a team of people who's job it is to do the necessary deals to extend our reach as far and wide as possible - whether just making the five minute bulletin available on a partner station or making an entire network available on an FM relay or emerging platform.

Re: [backstage] Why the poor bitrates on World Service, Asian Network etc?
Pretty sure the bombers use AM radio to check for the ongoing existence of Broadcasting House, and Sceptre isn't a bomber (they're all V class boats). Re the WS bitrate, these are worth revisiting, but it's possible that the budget and hence the bitrate for WS is entirely seperately worked out, being as the audience and funding is seperate. Arguably a high bit rate would be counter productive for WS- the aim of the game is to reach a lot of people at the end of thin wires (or over wireless). A parallel hi bit rate service might well be a useful way to get the quality out there, but then that's a stack more cash to pay, and not really in line with the WS objectives. Personally, I feel the biggest problem for WS is figuring out which audiences to focus on- getting it wrong can be painful- the Thai service shut down three years ago, sonce when we've seen two military coups and border war flare up. Can't help wondering if anyone at Bush House is regreting handing out those redundancies. a On Tue, Oct 21, 2008 at 3:29 AM, Christopher Woods [EMAIL PROTECTED] wrote: This one's a late night, in-the-kitchen thought.

(imvho of course, there are doubtless other factors weighing in on the decision but that is how I perceive it as a UK citizen from a plain ole consumer standpoint). Just seems odd more than anything else that where easy to do, the WS already has decent quality broadcast, and there's these big holes on other platforms where listening is like jumping back to the 90s and trying to squeeze every last baud out of your Hayes v.90 to stream that 32kbps station! :) - Sent via the backstage.bbc.co.uk discussion group.

The inappropriate argument may have held water four or five years ago, but is increasingly irrelevant these days. There are actually 2 problems here: The first is stupidly complicated, and I'm not sure I understand it all fully. But it boils down to the fact that we cannot spend grant in aid funds on a service targeted exclusively at the UK. A high bitrate stream using the existing BBC infrastructure GeoIP locked to the UK would be the wrong side of the rules, as we would have to pay BBC Technology/Siemens grant in aid money to provide the UK exclusive service. Even if the funding rules were not in place, I imagine there would be objections on editorial grounds to restricting access to our services. The second reason, is that the BBC Streaming Infrastructure was never really designed for delivering high bitrate streams outside the UK if we were to make them universally available. You could, perhaps, make high bitrate versions available to platform providers, with a limited number of feeds for the likes of LiveStation and Zattoo and the like. That would get them the BBC World Service in high quality and you would get your radio station distributed for free. If you make the feeds we could have a backstage competition to see who can get the highest listener to feed ratio? The last few servers the BBC had in New York were shut down a while back, so there are now no BBC servers outside the UK. So to launch a global high bitrate service could potentially have quality of service issues. This is actually the real hurdle to increasing the bitrates, rather than anything else. As it happens we will have completed migrating our radio and on-demand playout to an external CDN when the schedules change at the end of BST, so this solves the infrastructure problem. Once we have the minor detail of launching Persian TV out of the way, we will be looking at making additional formats and bitrates available - but in a way that does not affect those that still need the narrowband Real/Windows offerings. -- Gareth Davis | Production Systems Specialist World Service Future Media, Digital Delivery Team - Part of BBC Global News Division * http://www.bbcworldservice.com/ * 702NE Bush House, Strand, London, WC2B 4PH - Sent via the backstage.bbc.co.uk discussion group.
